Going To Experiment With An Active Gain Stage With Tubes!
Posted: Thu Sep 16, 2021 2:44 pm
This should be an interesting experiment. I was attempting to purchase the matching T3000 transformer from a seller on UKAudiomart, but he never responded.
In the process of looking around I came across a Conrad Johnson HV1. This is an active head amp but it uses Nuvistor tubes. Very few components do use this gain device, and all of them that I have heard sound remarkable. The price was quite reasonable, so I bought it last night. Should have it in about 5 to 7 days, and we are going to give it a shot with the MC3000.
This seems to be a forgotten head amp but was well received in the day. One owner posted it can be a bit microphonic, I wonder if that is due to the tubes they had installed. I also am curious if it inverts phase like some CJ components do, and if so I will take care of that at the cartridge leads as inverting speaker wires is a pain in the butt.
Should be a grand experiment!
